The AirTAC GFR60025C1TK AirTAC Filter Regulator NPT1 in is a genuine G-series filter regulator: water separation, 40 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT1" ports, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR60025C1TK is a size 600 filter regulator: it removes water and particulate from compressed air and holds downstream pressure in one body. This configuration is built with a 1 in NPT port, the standard 40 um filter element, a differential-pressure drain that bleeds collected condensate automatically as flow passes through, and an external round pressure gauge scaled in MPa. A reverse/check valve is fitted, and the size 600 bowl is aluminium alloy with a mounting bracket included.
This is a genuine AirTAC part. The GFR family spans sizes 200 to 600 with port sizes from 1/8 in to 1 in, optional 5 um filtration (code W), automatic, manual or differential-pressure drains, square or round gauges with MPa, psi or bar scales, and G, NPT or PT threads. Flow figures are published as curves rather than a single rating, so ask us to confirm the datasheet for your application before ordering.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). Air must not freeze in the unit. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

Field order is size, port, drain, type, bracket, gauge, shape, scale, grade, thread, reflux — a blank position takes the default. Example: GFR300-08 is a 300 body, PT1/4", differential drain, standard type, bracket included, gauge fitted, 40 µm, PT thread, no reflux valve.
A larger body carries a larger port and holds set pressure better as flow rises. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom. The GFR600 uses an aluminium-alloy bowl; the 200, 300 and 400 bodies use PC.

Filtering and regulating the compressed air feeding a spray booth, so water and pipe scale are stripped out and atomising pressure is held steady at the guns.
Supplying clean, regulated air to the clamping cylinders and tool-change actuators on a machining centre, where a steady set pressure keeps workholding consistent.
Conditioning the air that drives the cylinders and vacuum generators on a packaging conveyor, with the check valve holding downstream pressure during supply dips.
Step through the real choices before ordering. Size 600 with a 1 in port is the largest GFR step; if your line draws less air, a 400 or 300 unit on a smaller port may suit - match the size to required flow, which we confirm from the published curves on request. Drain options are differential-pressure (this unit), fully automatic, or manual; choose manual only where someone can bleed the bowl routinely. Filtration is 40 um standard or 5 um with code W - pick 5 um only where downstream equipment demands finer air. The gauge here is an external round gauge in MPa; psi or bar scales and the embedded square gauge are alternatives. Thread is NPT on this unit; PT is the catalogue standard and G (BSPP) is also orderable. A bracket is included; a J-code variant omits it.
Because flow is published as curves and not a single rated figure, send us your application details and we will confirm sizing against the datasheet before you order.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR series as curves rather than a single rated figure, so we do not quote one number. Tell us your application and we will confirm the flow from the datasheet on request before you order.
This unit's differential-pressure drain bleeds condensate from the aluminium bowl automatically as air flows through it - no operator action needed. If the unit will sit in a line with long idle periods, an automatic drain (code A) or a manual drain (code M) may suit better; all three are orderable options in this size.
